CPI W Series Thermal Switches Solve Unique Thermal Challenges
CPI Rod & Tube Thermal Switches are unique in the world for their extremely high temperature set points, their extreme reliability and their tight tolerances. The most recent variation of our W series Rod & Tube switch represents a small but important option in the product line wherein the case is grounded and a military grade connector is applied at the factory.
